e clen jars and condensers now in use ancl employecl at radio-telegraphstations ahcl the. like, occupy a rather large amount ofspace inrelation Leydciinow commonly usecl are of a. cylindrical shape orWithoiil; constricteol neck. If more jars are to he cow plecl togetherto increase thecapacity, it is necessary to place then either alongsideor and when coupled in seon top of each other ries a smaller jar largerone, but then, capacity becomes less.

The present invention relates to an im proved construction ofcondensers, the same beingniacle more or less of the shape Qiia cone ora hemisphere or ment,with the result that condensers of the 'same shapeand size can be placed ohe' insicle the other. These condensers may thenin lmowrimanner, be coupled in parallel or by groups in series, asdesired.

To increase the distance at the edge be tween the two coatings thecondensers may be provided withan outwar zlly projecting flange, whichmay he of clifierent shapes.

In electrolytic condensers, it has been pro posed to employ a nestedseries of pairs of metallic dishes or cones, members of each pair ofdishes being separated. by a correspondingly shaped dish ofinsulatingmaterial for the purpose of preventing the electrolyte from shortcircuiting members of a pair 'shoulcl one of-these become punctured. Thepresent invention however relates to. 'contype referred. to in which-theedges of the two metallic coatings are-sepais also placed; inside a asis wellknown, the
